i been reading more about it. seems like there's a watermark in the audio we can't hear that survives through conversion and if your device picks it up it'll shut you down. so mp4 removes that?
All I know is if I download a blu-ray movie its either in mp4, m4v or mkv. PS3 will not play mkv files (which are too large anyway) so mp4/m4v always works. If you're on a mac like me then use HandBrake to convert your files to mp4/m4v.
